Multilevel bipolar high voltage pulse source - interlock dead time reduction

In the paper, a distinctive method of generating high voltage pulses with high du/dt is investigated. The power stage of the proposed source consists of eight individual sources that can be arbitrarily connected in series to obtain the desired magnitude and a one-phase transistor bridge for the selection of the output pulse polarity. A special emphasis is put on the reduction of an interlock dead time when generating bipolar pulses.
